Subject: [PATCH] Fix library gql query caching issue

With 8b8da3033556a257badd03f1fcdadefaa15912bc the library now calls `useGetMigratableSources` which uses the same `mangas` query as `GET_LIBRARY_MANGA_COUNT`.
However, they select different fields, which causes the cache to get overwritte, because it apollo-client wasn't merging the results.
